This research was conducted at agric physical lab, Department of Animal science, Faculty of Agriculture to determines the effects of marinating spent layer meat with basil leaf paste on drip loss and sensory attributes under different post mortem conditions. In the light of this, the poultry industry is obliged to continuously grow for a steady supply of quality poultry meat. Marinating the spent layer hen's meat with fresh basil leaves (Ocimum basilicum) in addition to subjecting the meat to 0, 6, 12, and at 24 hours post mortem aging before cooking increased it's organoleptic attributes which was readily acceptable to consumers. Marination of meat with herbs or spices like basil leaves paste had enhanced consumer's preference for taste, texture aroma, colour and overall acceptance. Marination improved consumer acceptance of spent layer meat irrespective of parts and post mortem aging. However, the majority of the respondents preferred meat marinated and subjected to 12 hours of post mortem aging. It is recommended that more quantity of marinate should be added further studies should in order to determine more effect of fresh basil leaves rough paste. And more hours of postmortem aging should be increased in order to determine more effect of fresh basil leaves rough paste marinate.

Coffee beans are processed from coffee cherries by either natural, pulped natural, or washing. The aim of the present study was to evaluate the physiochemical and sensory characteristics of espresso coffees processed by different methods. The color of the washed coffee sample presented the highest value of lightness while the natural coffee sample presented the highest value of redness and yellowness. The biggest difference in brewed coffee, whether natural, pulped natural, or washed, was in the TDS content, which was higher in natural coffee and lower in washed coffee. Sensory descriptive analysis and acceptance test for espresso coffee using a 15 cm line scale were carried out by 12 trained panelists. Natural coffee had the highest cherry-like flavor and sweetness taste while washed coffee had the highest citrus flavor and acidity taste. An important attribute of espresso coffee is body, and natural coffee presented strong body while washed coffee presented a low body attribute. In conclusion, significant differences were observed among the three processing methods of green coffee. Pulped natural coffees presented intermediate physiochemical and sensory characteristics compared to washed and natural coffee. Natural coffees are appreciated for their increased body, and washed coffees are appreciated for added citrus flavors and acidity espresso coffee blends.

Quality changes of cooked meat products are dependent upon cooking temperature and heating methods. Pork ham is the most preferred pork dish using pork hams in South Korea although it is not suited to various cooking methods because its low fat content does not provide desirable physiochemical and sensory properties to consumers. Therefore, the objective of this study was to evaluate the effect of four different cooking methods on pork legs by comparing Ocoo, Sous-vide, steaming, and boiling technique at $80^{\circ}C$ and $100^{\circ}C$. Ultimately, the most effective cooking method and temperature to improve the quality of cooked pork hams was investigated. As the results of texture analysis, the samples cooked using Ocoo and Sous-vide methods showed higher springiness and cohesiveness than those using steaming and boiling methods. For the sensory evaluation, participants liked the hardness, juiciness, chewiness, tenderness of the samples using the OC method, resulting in the highest overall acceptance rate. The results of this study showed that using Ocoo or Sous-Vide cooking methods can improve the quality of cooked pork hams in both physicochemical and sensory properties.

This study was carried out to determine the quality characteristics of Jeju mandarin orange jellies containing sugar (control) and sugar derivative sweeteners (erythritol, isomaltooligosaccharide, sorbitol, and xylitol) to be consumed by the elderly. The gelling agents were carrageenan and gellan gum at the concentration of 0.27%, respectively. The average age of the subjects for the acceptance test was 78. The lightness (L), redness (a), and yellowness (b) values of the carrageenan gel were higher than those of the gellan gum gel using the same sugars. The L, a, and b values of the carrageenan gel made with sugar derivative sweeteners were higher than those of the respective gel made with sugar. Whereas there were almost no differences between the color values of the gellan gum gels made with sugar and sugar derivative sweeteners, respectively. The gelling and melting temperatures of the carrageenan gel with erythritol were highest and those of the respective gel with xylitol were lowest among the sugar derivative sweeteners. The gelling and melting temperatures of the gellan gum gels with erythritol and isomaltooligosaccharide, respectively, were lower, and those of the respective gel made with xylitol were higher compared to that with sugar. There was no break down in the gellan gum gel. The break down rate of the carrageenan gel made with isomaltooligosaccharide was highest and that of the respective gel with xylitol was lowest among the sugar derivative sweeteners. The hardness, adhesiveness, springiness, and chewiness of the gellan gum gel were greater compared to the carrageenan gel. The adhesiveness levels of the carrageenan gels made with sugar derivative sweeteners were lower, and their springiness was higher than the respective gel with sugar. All the TPA characteristics of the gellan gum gels made with erythritol and xylitol, respectively, were higher than the respective gel with sugar. The rupture properties of the gels were the same as their TPA characteristics. The sensory acceptance of the carrageenan and gellan gum gels made with sugar were highest among all the sweeteners. There were no significant differences in the sensory acceptance scores of the carrageenan gels made with xylitol, erythritol, and sugar, respectively, and there were also no significant differences in the sensory acceptance scores of the gellan gum gels made with xylitol, sorbitol, and sugar, respectively. Xylitol was preferred in both the carrageenan and gellan gum gels. Thus, xylitol appears to be an appropriate alternative sweetener to sugar in Jeju mandarin orange jelly for consumption by the elderly, with regard to the acceptability and stability of the gel.

This study developed a new yanggaeng(red bean sweet jelly) by adding Peucedanum japonicum powder from 5% to 20%. It has been evaluated its physicochemical, sensory characteristics and antioxidant activity. The DPPH radical scavenging activity of Peucedanum japonicum powder was 40.53% and the total phenolic compound content was 13.36 mg/100 g. Moisture content of yanggaeng with Peucedanum japonicum powder added 5~15% was 50.24~48.32% significantly higher than in the control group(p<0.05). The hardness of yanggaeng was $2,748.25g/m^2$in control and the PY5 and PY10 were $4,012.05g/m^2$ and $4,019.40g/m^2$ respectively, significantly higher than control(p<0.05). However, when the amount of Peucedanum japonicum powder was increased by more than a certain rate, it decreased again, as $2,155.39g/m^2$ in PY20. As a result of the acceptance test of the yanggaeng, the flavor of yanggaeng with Peucedanum japonicum powder was evaluated significantly higher than control(p<0.05), but PY20 was 5.20 not significantly difference with PY10. The overall acceptance of the yanggaeng showed the lowest value of 4.00 in the control, PY15 showed significantly high value as 7.80(p<0.05). Compared with the control, the acceptance of samples with Peucedanum japonicum powder 5~15% was higher than that of control. It was concluded that 10% and 15% of the Peucedanum japonicum powder could be added for the development of the yanggaeng. According to the above study result, to enhance the utilization of Peucedanum japonicum for developing functional food would be possible, and a new yanggaeng product by adding Peucedanum japonicum would have good potential.
